Abstract The article analyses the September 2007 European Commission proposal for a third internal energy policy package, agreed by the European Union in spring 2009. Compared to legislation from 2003, the proposal reflects greater will on the part of the Commission to pressure unwilling Member State governments, and shifts in Commission leverage vis-a-vis Member States as well as a shift in policy networks with clout in EU policy-making. This shift in Commission leverage would indicate stronger supranational governance in EU energy matters in the future.
